3.5 mile commute, all but the worst weather:
Same rear light as pic above, plus an extra cheap on on my RHS. Exposure Joystick up front.
Front mudguard – One of those £7 under the fork jobs, cant remember the name.
Rear mudguard – Not essensial, make your bike look rubbish but very useful. Need to get one really.
Full cycle gear, dont want to turn up to work sweaty with wet, muddy, ripped trousers. Its also a lot more comfy to cycle in cycle gear and faster.
